ArrayFire: toString
Print the array to a string instead of the screen. More...
AFAPI void toString (char **output, const char *exp, const array &arr, const int precision=4, const bool transpose=true) AFAPI const char * toString (const char *exp, const array &arr, const int precision=4, const bool transpose=true) AFAPI af_err af_array_to_string (char **output, const char *exp, const af_array arr, const int precision, const bool transpose)
Print the array to a string instead of the screen.
This function is similar to af::print, except that it prints to a string rather than to screen.
◆ af_array_to_string() AFAPI af_err af_array_to_string ( char ** output, const char * exp, const af_array arr, const int precision, const bool transpose )
-
Parameters
-
[out] output is the pointer to the c-string that will hold the data. The memory for output is allocated by the function. The user is responsible for deleting the memory. [in] exp is an expression, generally the name of the array [in] arr is the input array [in] precision is the precision length for display [in] transpose determines whether or not to transpose the array before storing it in the string
◆ toString() [1/2] AFAPI void toString ( char ** output, const char * exp, const array & arr, const int precision = 4, const bool transpose = true )
-
Parameters
-
[out] output is the pointer to the c-string that will hold the data. The memory for output is allocated by the function. The user is responsible for deleting the memory using af::freeHost() or af_free_host(). [in] exp is an expression, generally the name of the array [in] arr is the input array [in] precision is the precision length for display [in] transpose determines whether or not to transpose the array before storing it in the string
◆ toString() [2/2] AFAPI const char * toString ( const char * exp, const array & arr, const int precision = 4, const bool transpose = true )
-
Parameters
-
[in] exp is an expression, generally the name of the array [in] arr is the input array [in] precision is the precision length for display [in] transpose determines whether or not to transpose the array before storing it in the string
-
Returns
-
output is the pointer to the c-string that will hold the data. The memory for output is allocated by the function. The user is responsible for deleting the memory using af::freeHost() or af_free_host().
